Configure channel pad and channel number

[phcella]

Here in Brazil, we have DTV (digital tv) and it has some channels in one channel number as you can see on the image below

I would like to know how I need to write the channel number on the configuration.

And another problem, after I click on the Channel Logo, appeared an error: "Failed to call the service media_player/play_media.'NoneType' object is not iterable". You can see the screenshot below

I have the same problem, I don't know how to add DTV channels with their logo.
